A1020B-1PLG68I

Field Programmable Gate Array Overview

The A1020B-1PLG68I is an embedded Field Programmable Gate Array (FPGA) from the Microsemi ACT™ 1 series. It features a logic capacity of 2000 gates organized into 547 LABs/CLBs and provides 57 user-accessible I/O pins. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 68-LCC package with J-leads, specifically identified as a 68-PLCC supplier device package measuring 24.23x24.23 mm. It is rated for industrial temperature operation between -40°C and 85°C. The component has a Moisture Sensitivity Level (MSL) of 3, corresponding to a 168-hour limit at peak reflow conditions.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing single-chip ASIC alternative capabilities
• CMOS technology supporting mixed-voltage operation for core and I/Os
• Industrial temperature rating for extended environmental reliability

Field Programmable Gate Array Applications

• Embedded control systems requiring moderate logic density
• Interface bridging between legacy 5V components and modern digital logic
• Prototyping for applications transitioning from fixed-gate-array designs

Field Programmable Gate Array Procurement Notes

This component is officially classified as obsolete by the manufacturer, with obsolescence notices dated June 21, 2013. Verification of authenticity is critical when sourcing from secondary markets due to the long production discontinuation timeline. Buyers must confirm the specific suffix '1' indicates the correct speed grade and that the package matches the 68-LCC physical dimensions before integration into new designs.

Field Programmable Gate Array Selection Notes

Engineers selecting this part should note its position within the ACT™ 1 family, sharing architectural traits with the A1010B but offering higher gate counts. The 68-pin LCC package limits pin availability compared to QFP variants. Designers must account for the 4.5V to 5.5V power requirement, ensuring compatibility with existing system rails without additional level shifting for standard 5V logic interfaces.

Field Programmable Gate Array Part Context

The A1020B-1PLG68I belongs to the broader A1020B product line, which includes variants like the A1020B-1VQG80I and A1020B-2PLG68C. These parts share the same 2000-gate logic fabric and 547 CLB structure but differ in package types and speed grades. The '1' suffix typically denotes a specific performance bin within the ACT™ 1 generation, distinguishing it from the commercial grade 'C' variants.

Field Programmable Gate Array Replacement Considerations

Public documentation confirms no direct active substitutes. The A40MX02 series offers similar gate counts but utilizes different MX FPGA architecture. Legacy replacements may include other ACT™ 1 devices such as the A1020B-2PLG68C, though these require verification of speed grade compatibility and package footprint alignment.
